There is, sadly it is at the SGI Addict (www.sgiaddict.net) which is
inconsistently up. This is most useful for the older sleds with
integral connectors, modern SGI sleds are (I believe) one of three
types: O2 (wouldn't come close to fitting), Octane/Origin200/000/Onyx2
(works), and Origin300/000

A drive with a 1" long connector very similar to a SCSI SCA connector
is probably FC (Fiber Channel). If you have a newish Sun (Blade
1000/2000 era) you can check, as the main interface in these is FC.
The FC drives I have (Seagates) have a model number ending in FC. Some
of the SGI Vaults/InfiniteStorage arrays do use FC disks, so it's
possible that these came out of one of those. Sadly, I'm not sure that
the Qlogic FC interfaces are bootable, so you might not be able to use
them as a system disk.
